INKING MECHANISM FOR ROTARY PRINTING-MACHINES.

To all fle/0m t may concern Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Inking Mechanism for Rotary Printing-Machines, of which the following is a specification.

In inking mechanism for rotary printing machines where the several composition rollers of the mechanism are left in contact with one another and with the cylinders when idle, there is a tendency on the part of the rollers, beca-use of their stationary contact, to become flattened or distorted and thereby destroying their usefulness.

Furthermore, because of their contact, it consumes a considerable period ot' time to thoroughly clean the rollers.

This invention includes means whereby the several composition rollers may be moved into and out of Contact with their coacting rollers and cylinders, with the objects in view ofleaving the rollers out of contact when standing idle, to prevent the flattening or distortion thereof above referred to; to permit the thorough and inde.- pendent cleaning of the rollers while out of Contact without removing them from the machine; and to facilitate the removal or replacement of any one ,of the rollers. l

This invention also includes more specifically a single means for moving the form rollers into and out of contact with their vibrating rollers; a single means for moving the carrying rollers into and out of contact with their ink cylinders and vibrating rollers; and a single means for moving the distributing rollers into and out of contact with their ink cylinders; the set of form rollers and the set of distributing rollers being' mounted in auxiliary frames hinged to the roller frame, the carrying rollers being mounted .in movable bearings carried by the roller frame, and the ink cylinders and vibrating rollers being mounted in fixed bearings in the roller frame. Means are also provided for removably securing the roller frame to the main frame and a common means is provided for 'simultaneously moving the roller frame and the form cylinder in the same direction, whereby the form cylinder may be kept in contact with its .form rollers as the roller frame is moved away from the main frame.
